Contrast Agent Pooling in the Descending Aorta Due to Severe Heart Failure.

Case Presentation: An 86-year-old female presented to our emergency department with chest pain and orthopnea and was diagnosed with heart failure and ST-elevation myocardial infarction, prompting hospitalization. During hospitalization, she developed a fever. A chest and abdominal contrast-enhanced computed tomography (CT), conducted to investigate the cause of the fever, coincidentally revealed sedimentation of contrast agent in the descending aorta.

Improvement of Mucoid Impaction with Dupilumab in a Severe Asthma Patient.

Different from intrabronchial mucus accumulation in bronchiectasis caused by chronic inflammation, mucoid impactions are observed in patients with allergic bronchopulmonary aspergillosis (ABPA) and bronchial asthma. A 62-year-old man was referred to our hospital for treatment of bronchial asthma. Five years ago, he had a coronary stent insertion for myocardial infarction and was diagnosed with bronchial asthma.

Development of Pseudochylothorax in a Patient with Lung Squamous Cell Carcinoma and Rheumatoid Arthritis.

Pseudochylothorax is a rare disease entity. It is characterized by a milky white pleural fluid with a cholesterol/triglyceride ratio >1. According to published reports, most patients had associated diseases, including rheumatoid arthritis and tuberculosis, with only one patient having oropharynx carcinoma associated with lung metastases.

Investigation of age and smoking in NSCLC patients with uncommon EGFR mutations.

Introduction: In addition to the two common epidermal growth factor receptor (EGFR) mutations, there are many uncommon mutations. Due to the high number of uncommon types, as well as the rarity of patients, there is lack of information regarding patient demographics, especially age distribution and smoking status. Against this background, we conducted an analysis to clarify the background of patients with uncommon EGFR mutations, especially considering their age distribution and smoking status.

Patient Age and -positive Non-small Cell Lung Cancer: A Multicenter Retrospective Study.

Background/aim: The median age of subjects in many clinical trials of epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitor conducted to date has been approximately 60 years. However, it is not uncommon to encounter EGFR gene-positive patients in their 70s or 80s. Based on information obtained from these clinical trials, EGFR gene-positive non-small cell lung cancer (NSCLC) patients are considered to be younger than EGFR-negative patients.

Moyamoya Syndrome: Differential Diagnosis in Patients With Central Nervous System Symptoms and Hyperthyroidism.

Moyamoya syndrome, known as secondary moyamoya disease, is associated with various primary illnesses, such as brain tumor, meningitis, autoimmune disease, and thyrotoxicosis, and their relations are not clear. We report a rare case of moyamoya syndrome in a patient with Graves' disease. An 18-year-old woman was admitted to our hospital due to convulsions.

Mesalazine-Induced Diffuse Lung Injury in a Patient Without Respiratory Signs and Symptoms.

Mesalazine is a drug used to treat ulcerative colitis and Crohn's disease, and is known to rarely cause lung injury. We show herein a unique case who developed this drug-induced injury. A 17-year-old boy presented with fever and anorexia after administration of mesalazine.

Rapidly Progressive Interstitial Lung Disease Associated with Melanoma Differentiation-Associated Gene 5 Antibody.

Anti-melanoma differentiation-associated gene-5 (MDA-5) antibody is an autoantibody found in patients with dermatomyositis. These antibody-positive patients are clinically characterized by complications of rapidly progressive interstitial pneumonia resistant to treatment and with poor prognosis. We describe herein a patient with MDA-5 antibody-positive interstitial lung disease, which progressed rapidly to death after a period of slow progress.

Classification of schizophrenia patients and healthy controls using p100 event-related potentials for visual processing.

The study of event-related potentials (ERPs) is capable of elucidating the abnormalities in brain network dynamics relevant to the information-processing deficits in schizophrenia patients. In contrast to P50 and P300 ERPs, however, the results of P100 ERP studies in schizophrenia patients are less consistent. We have previously reported that P100 amplitudes did not differ significantly between patients with schizophrenia and healthy subjects.
